Abstract: In order to repair a workpiece, a requirement specification about a requirement to be met by the workpiece and a numerical simulation model for simulating a physical behavior of the workpiece are imported. Furthermore, a current shape of the workpiece is detected by means of a sensor. Where a deviation of the current shape from a target shape S of the workpiece is identified, a respective physical behavior of the workpiece in its current shape and in a shape added to by means of a 3D printer are simulated using the simulation model. Furthermore, a check is performed on the basis of the requirement specification to ascertain whether the simulated physical behavior meets the requirement. Depending on the outcome of the check, the workpiece is then either left in its current shape, added to by the 3D printer or discarded.

Abstract: An apparatus having a layer of fats, oils and grease (F.O.G) on water includes a tank having an inlet and an outlet. The inlet connects to a source of F.O.G.-laden effluent and the outlet connects to a sewer pipe so that the outlet defines a normal static water level for F.O.G. and effluent in the tank. A sensor mounted above the static water level determines a distance from the sensor to a top of F.O.G. within the tank, so that a thickness of the F.O.G. in the tank can be determined. If the sensor is LIDAR, sensing may be at about 940 nm. When the F.O.G. is sensed to be above a threshold, the apparatus generates signals to remove the F.O.G. Ultrasonic sensing may be used. Preferably, the sensor is mounted far enough above the static water level so the distance between the sensor and the liquid surface is filled with air. More preferably, the sensor is far enough above the static water level so that the top of the F.O.G. does not touch the sensor even as the top of the F.O.G.
